Furthermore, ultralow mowing heights during
hot weather makes turf vulnerable to disease and
reduces its ability to tolerate other stresses such as
insects, traffic, drought, shade and poor drainage. As
a result, there is a serious risk of turf loss, which can
lead to bumpy playing conditions and lost revenue.
At minimum, extra resources will be needed to
maintain acceptable putting green quality when
heat-stressed turf is mown extremely low.
Golfers can help keep putting greens healthy
and smooth during hot weather by being patient

with temporarily slower green speeds. A well-timed,
conservative decision to raise the mowing height
could be the difference between healthy and dead
putting greens.
Next time you see a superintendent checking
putting greens on an extremely hot afternoon, be
sure to express interest and understanding in the
steps that are being taken to protect the putting
greens from summer heat stress. Working together
is the best way to protect a golf course.
